how I can add a ComboBox column to an unbound GridView through code at runtime.
View 1 Repliesi have a gridview populated by the code below:
protected void CautaProiect_Click(object sender, EventArgs e)
{
wipDBTableAdapters.GetSummaryProiectTableAdapter proiecte = new wipDBTableAdapters.GetSummaryProiectTableAdapter();
SummaryGrid.DataSource = proiecte.GetData(CodProiect.Text);
SummaryGrid.DataBind();
}
The gridview will be populated with some columns with values.
The problem is that the values are formated like this 1234.5600 and i want them to be like 1,234.56
I have a unbound checkbox column in the GridView control.
When i try to get the value of checkbox in the C# code the checkstate is always false.
I want to check if the Checkbox is selected in a row and get the values of all the cells in that row.
CheckBox chkSelect= (CheckBox)GridView1.Rows[1].FindControl("chkSelect");
<asp:GridView
runat="server"
ID="GridView1"
AutoGenerateColumns="False"
[Code].....
Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
View 1 RepliesI am populating a DataTable and binding it to a GridView's source.
I have a dropdown box in an itemtemplate in the gridview.
I want the dropdown to have 3 options and depending on what is in a column from row in datatable a specific value will be selected.
I was able to do this when I was binding gridview source by looping through SQL but now I that I am putting the results in a datatable I am not sure how to go about it.
I have a gridview populated by the code below:
[Code]....
This will create multiple fields in the gridview with some values.
Say i have this field called "Sold" and it has the value "1234.5600"
How can i display it like "1,234.56" ?

i use a gridview to show data from datasource, but i have some column in this gridview that they're not bound. If i go in edit mode, my unbound control show me the textbox to enter value and its ok, but if i modify value thru rowdatabound, now when i go in edit mode, the textbox are not showing as i expect, its just showing the value i put in rowdatabound, but i don't have the textbox to let me enter a new value and update it after.
And more in the same relation: with the two above condition i wrote, when i dont modify value in rowdatabound, i can modify value in prerender event with this line:
TextBox
box1 = this.GridView1.Rows[this.GridView1.EditIndex].FindControl("TextBox1")
as
TextBox;
box1.Text = "a value"
;
but
when again i modify value in rowdatabound, the line above will not work too, box1 is load with a null value
I have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.
View 2 RepliesIs it possible that once I have created a datatable programatically, I can then sort that datatable before binding it to a asp:repeater? I have a number of records that I have to get from a com object that has not been eliminated. The com object populates an array, then I loop through the array to pull data from my datatbase, adding the db data to the datatable. Then I bind the datatable to a repeater.
1) the array is multidimensional
2) The COM object doesn't sort the data by company ID (which is what I need to do)
I have an unbound dropdownlist that is populated in my page_load event. I want to retrieve the text of the selection from the dropdownlist. I'm
using dropdownlist.selectedvalue.tostring(), which works on original page_load but not when I make another selection, even though autopostback is set to true. Do i have to write something in the selectedindexchanged event when not databinding?
Reorder list control cannot be set to not postback? My hope for this control was that I could tie it to a list of data (either a datasource or even a manually created list) and then allow the user to move the items in the list up and down until they liked the new order of all of the elements. They then would click a button to save the updates to the database. Is this possible? It seems that after every reorder there is a postback requried to the datasource to perform an UPDATE, even if the PostBackOnReorder
="false"
value is set.
So if my list is
1 Atlanta
2 Boston
3 Chicago
4 Denver
5 Edmonton
and they want to switch Denver with Boston and then hit the Update List button I could cycle through the list an only update two entries rather than all 5 entries twice (for each Postabk on reorder)
How to populate dropdownlist in a gridview by selecting another dropdown in same gridview

I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn
1 1111 2222 3333 Yes / No (selected Yes)
2 2222 3333 4444 Yes / No
GRIDVIEW2
ID NotesColumn
1 Texbox displays here
how to display data in a gridview2 which is depends from the selected row in gridview1?
View 1 Repliesthere is a radio button, a dropdownlist. radiobuttons are OY, OTY,VDA ( in my database there are fields named OY.OTY,VDA) if i select OY in my radio button the data should be displayed from field OY in dropdownlist and if i select OTY in my radio button the data should be displayed from OTY field in dropdownlist is it possible. there is a sqldatasource for dropdownlist .
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:MS16ConnectionString %>"
SelectCommand="SELECT DISTINCT OY FROM COURSE_INTAKE">
</asp:SqlDataSource>
THE SELECTED DROPDOWNLIST DATA IS REQUIRDE TO BE DISPLYED IN A GRIDVIEW.
Alright, so I have a Gridview which is bound to a stored procedure. The stored procedure uses cross tab functionality to count customer data / types, and then display it like this ...
Code:
[code]....
Now this is where I'm stumped ... each data cell (or cell that displays the count of data for that column / row), need to be a link, and upon clicking that link, a pop up or something will bring up another gridview or list listing all those clients or customers. For example, if you click on row 2, cell 2 (519), then it will open a gridview or list of all 519 of those clients. This basically means each cell will have to represent a different query, unless I use dynamic sql somehow... Does anyone have any idea how I might be able to accomplish this.
Suppose I have a e-shop web app. I have a product categories table in my database that populates a gridview using sqldatasource.
I want to be able to click on the select hyperlink on a row and use that event to populate ANOTHER gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
I have two gridviews on a form. When the user selects a row from the first gridview the second gridview should populate based on the selected row. The second gridview is not generating as expected. If I remove the "@vendor_id_fk" from the WHERE clause of the query and replace it with a value, the second gridview generates when a row is selected in the first gridview. So I know that's where the issue lies, but I am having some difficulty solving the problem.
Here is the aspx:
<div class="row">
<%--Vendor List--%>
<asp:GridView
ID="gv_vendor_list"
AutoGenerateColumns="false"
AllowPaging="true"
AllowSorting="true"
ShowFooter="true"

I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56
13.35
1442.22
...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?
The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

i have a DetailsView that is populated by a Linq to Entities query. Example query is below.
Dim leaveApp = From L In db.CompassionateLeaveApplications _
I usually use repeaters all the time but have used a gridview control so I can take advantage of the row_editing feature.
I had it all working but then needed to replace the standard linkbutton "Edit" with an image.
Its all gone horribly wrong and revealed my lack of understanding with this control.

I need to populate gridview on rowdatabound because I may need to disable whole row amnd I want to swap images about.
I think im going wrong because I should eb databinding using the <% eval %> method, but im not really sure.
